Improvement in Boxes.

UNITED STATES ROBERT B. DAVIS, OF NEW YORK, N. Y.

IMPROVEMENT IN BOXES.

Specification forming part of Letters-Patent No. 126,272, dated April30,1872.

To all whom it may concern:

Be it known that I, ROBERT B. DAVIS, of the city, county, and State ofNew York, have invented a new and useful Improvement in Boxes; and I dohereby declare the following to be a full, clear, and exact descriptionthereof, which will enable those skilled in the art to make and use thesame, reference being had to the accompanying drawing forming part ofthis speciication, in which draw- 1n g- Figure l represents a verticalcentral section of my invention. Fig. 2 is an inverted plan of the headdetached. Fig. 3 is a vertical central section of a modification of mybox. Fig. 4 is an inverted plan of its head or bottom. Fig. 5 is anothermodification of my box. Fig. 6 is an inverted plan of its head orbottom.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a supporting-shoulder andof an outside ange on the head or bottom of a box in such a manner thatbetween said shoulder and flange an annular space is formed for thereception of the edge ofthe body of the box, and by these means the boxis materially strengthened, particularly against external pressuretending to crush the same. If the head of the box is made of sheetmetal, the supportingshoulder may be formed by spurs punched out of themetal composing said head, and leaving said head perforated, so thatwhen the outside covering of the box is removed the box y can be usedlike a cruet. In some cases the supporting-shoulder is formed bypunching the centra-l portion ofthe head down.

In the drawing, the letter A designates the body of my box, which may beconstructed of paper, pasteboard, sheet metal, or any other suitablematerial. On this body is fitted a head, B, and a bottom, C, both ofwhich are formed with a supporting-shoulder, a, fitting nicely in theinterior of the body, and with an outside flange, b, projecting over theedge of the body7 as shown in Figs. 1, 3, and 5 of the drawing. Saidhead and bottom are, by preference, made of sheet metal, and in thiscase the supporting-shoulder may be formed of a series of spurs, whichare punched in, as shown in Figs. l and 2.

By the operation of punching in said spurs perforations c are producedin the head, and if the outside covering is taken off the contents ofthe box, when in the form of a powder or in a granulated state, can beeasily discharged without removing the head. The supporting-shouldermay, however, be also formed by fastening to the inner surface of thehead or bottom a piece of pasteboard, wood, or other suitable materialof suflicient thickness to perform the desired object, and of such asize as to fit the b ody of the box, (see Figs. 2 and 3;) or, ifdesired, the central portion of the head or bottom may be stamped down,as shown in Figs. 5 and 6, so as to produce the requiredsupporting-shoulder.

In either of these two last-named cases a continuous annular space isformed between the supporting-shoulder and the outside flan ge for thereception of the edge of the body ot the box.

By this arrangement great strength is imparted to my box, and thecontents 0f the box are not liable to leak out if said box should beexposed to an external pressure which would be liable to crush a box ofthe ordinary description.

What I claim as new, and desire to secure by Letters Patent, is-

The head or bottom of the box A, provided with an outside flange, b, andan inner supporting-shoulder, as shown, all constructed and arrangedsubstantially as described, for the purpose set forth.

This specification signed by me this 20th March, 1872.
